'VENTILATOIIL Application mea ocioter 1, 1925. serial No. 59,890.v

This invention relates to a ventilator, useful for many purposes, butmore especially adapted for use as a closure for transoms, doorways,windows, panels, or the like.

An object of the invention is toprovide a ventilator of the generalnature of those described and illustrated in my Patents, No. 1,519,553,granted December 16, 1924, an2d No. 1,529,037, granted March 10,1925,and No. 1,666,218, granted April 17,. 1928, and

resenting advantageous characteristics and eatures of construct-ionwhich are improvements over the disclosures of said patents.

A further and morespecific object is to provide aventilator consistingof a. frame having aplurality of louvers pivoted therein to turn ontheir axes'and preferably so proportioned and arranged that when swungin one direction they will completely close the space within the frameand when swung in the other direction will leave passage ways betweenthe respective louvers without opening a direct line of vision throughthe frame, and to equip 'the ventilator with improved operatingmechanism for swinging the louvers to open and closed position, whichoperating mechanism will be eiiicientfand dependable, and of simple andeconomical construction.

A still further object is to provide a ventilator consisting of a frameand a plurality of louvers pivoted therein as,stated, wherein thepivoted louvers will themselves cooperate with certain of the framemembers to cl'ose end spaces ir the frame when the louvers are ofpeculiar construction and have flanges extending outwardly of the frame,the whole frame being constructed to accomplish advantageous resultsdesired in a ventilator of the present general character, certain ofAwhich results are: (l) interlapping of the ends of the lovers with theinwardly extendin iianges of plates adjacent the louver ends (2%4closure of theend spaces 1n the .frame and parallel with the louverswhen sald louvers are'closed, by direct engagement of outermost louverswith plates of the frame adja-l -tively to each other whereby4 t-heplates can be more easily welded or otherwise secured together toproduce the frame than vcould individual plates of a frame wherein allofthe plates had inwardly extending ianges; and (4) a construction andarrangement of outer plates (thosewhich are of the peculiarshape to bedescribed) adapted to render the incorporation of the'finisliedventilator in a structure a simple task; that is to say, a constructionand arrangement of plates better suited to the insertion of a screw orscrewsin the ventilator and in a'structure to holdthe ventilator. s

And yet another object is to provide in the ventilator an operatingmechanism which, while of very simple and economical construction, willbe designed to provide for manipulation of the louvers to closed and toopen position by the expenditure of but a minimum of manual effort.

With the above objects in view, as well as vothers which will appear asthe specification proceeds, the invention comprises theA constructlon,arrangement and comblna-tion of parts as now to be fully described andas.

hereinafter to be specically. claimed, it being understood that thedisclosure herein is merely illustrative and meant to in no way limitthe spiritl of the invention, changes in details of construction andarrangement .of parts being permissible so long as within the scope ofthe `appended claims.

The ventilator of lthis invention is constituted by a liframe ofrectangular configuration, louvers pivoted therein, 'and mechanism forswinging the louvers on their pivots to open and close the spacewithinthe frame.

The frame, as shown, is composed ofsheet .metal, it consisting ofa topmember 10, a

bottom memberll, andside members, denoted 12 and 13, respectively. Allof the members of the frame are flanged plates. the

top and bottom members having flanges, de`

noted 14 and 15, respectively, extending out.- wardly for the fulllengths of said members from theirzopposite edges, and the side membershaving flanges 16 extending inwardly,

. preferably at right-angles, for the full lengths of said members fromtheir opposite edges.`

A manner in`which the members 10, 11, 12 and- 13 may be joined is bestshown in Figs. 4 and 5, wherein an end portion of a member, such asmember 10 in Fig. 4, and 11 in Fig. 5, and its flanges, 14 in Fig. 4,and 15in Fig. 5,

f' are drawn or offset inwardly, as denoted at 17, and the flanges 16'ofthe members 12 and 13, respectively, fit. snugly over the drawn in oroffset port1ons 17 to align with the flanges 14 and 15, respectively.The connection be tween the members 10 and 12, 13, and betweenl themembers 11 and 12, 13, may be made in any suitable manner, as, forexample by welding the plates to eachother at the four corners of theframe.vv In the finished frame, all of the flanges 14, 15 and 16 eitheralign, or are parallel.l See Figs. 2, 3, 4 and 5. Thebody portions ofthe plates 12 and 13 may be'tlat as disclosed. The body portions of theplates 10 and 11 are of the peculiar construction presently to bedescribed. vAswillfbe very clear from Figs. 4 and 5, the outer edges,denoted 18 and 19, respectively, of the flanges 14 and 15 preferablyterminate flush with the ends, v denoted 20, of l.the flanges 16,andwith the, ends,v denoted 21 and 22, respectively, of the'v mannerbest shown in Figs. 2, 3, 6, 7 yand 8. Thatlis to say, each louver 23has an ear 24 upon its arm 25 pivoted upon the member 12, and an ear 26upon this same arm pivoted upon the member 13, the arm 27 of each louverbeing free of ears. The ears 24 and 26 preferably extend at right-anglesin the same direction from the arm 25 of the louvers 23, and, as shown,the ears 24 are situated within the space between the arms 25- and 27,while each ear 26 has an extension 28 in the plane of the ear 26 butprojecting obliquely therefrom and terminating slightly beyond theadjacentarm 27. SeeFigs. 2 and 3. Each of the ears 24 is provided with ahole rotatablyreceiving a drawn portion 29 of the metal of the member orplate 12 of the frame, and each of the ears 26 is drawn as at 30'torotatably enter an annular flange 31 consisting of upwardly`orinwardly draWn metal of the member or-V plate 13 of the frame, thepivotal points for the louvers being arranged adjacent the opposite endsof the arms 25 thereof' net,far from the midwidths of said arms.

Numeral 32 denotes an operating'bar for manipulating' the louvers. Theoperating bar is arranged beneath the extensions 28 of the ears 26 toslide upon the plate 13 of the frame and each of the extensions 28 hasmetal dra-Wn therefrom and rotatably entering holes 33 at uniformdistances apart inthe operati/ng bar.A V

The mechanism for moving the operating bar longitudinally to turn thelouvers on their pivots consists of a manipulatinglever 34 having anopening 35 in its inner end portion l adapted to fit upon an end annularflange 31, as indicated more clearly in Fig. 8, and also having anopening 36 adjacent the opening 35 adapted to rotatably and snuglyreceive the preferably circular end 37 of the operating bar 32. Adjacentthe opening 36 (at the side thereof having the operating bar), the

operatirggbar. See Figs. 8 and 9. Evidently,

`the metal t138 could be cut away, but then:

the cro ctional area of the manipulating lever would be considerablyweakened. An

. metal of the manipulating leven 34 is offset,

intermediate portion, denoted 39, ofthe manipulating lever is movable inan elongated slot 40 in a flange'16 adjacent the frame member or plate13 (see Fig. 1), and adjacent the slot (just beyond said flange 16),the' metal Yofthe manipulating lever has a quarter-cir- .;,cle twist 41providing a finger piece 42 wh1ch preferably perpendicular to thebodyofthe member or plate 13, whereby the manipulating lever c-an be readilyoscillated to open and close the louvers, as will be understood.

It will be evident that the manipulating lever works about said endannular Harige 31 as a fulcrum of a lever of the second class, therotatable engagement of .saidmanipu- `ing lever can bear a relation tothe-inner portion thereof requiring the expenditure of but a minimum ofmanual effort to throw the louvers toward open or closed position. Itwilll also be evident that the component parts of the operatingmechanism and of'the ventilator are so associated and related that each`part is lixedly situated in the ventilator. The inner end portion of themanipulating lever is located between an ear 26, including its extension28, and the member or plate 13. The outer portion of said lever islocated by the slot 40. The rounded end of the operating bar is locatedby the manipulating lever and the offset portion 38 thereof,being-located be# tween said offset portion and the plate 13,

y and the whole length of said operating bar 1s located by theextensions 28 of the ears 26 of the louvers. l

The drawing of the metal of the member or plate 13 of the frame upwardlyor inwardly to form the annular flanges 31, provides a space 43 betweenthe extensions 28 of-the ears 26 of the louvers and said member or plate13 to afford clearance for the longitudinal sliding movementsof theoperating bar upon the member or plate 13. l See Fig. 7.

In Tfigs. 1 and 2 the louvers are ,shown in wide open position. vIn saidfigures, all of the arms 25 are parallel and spaced at equal vdistancesapart, as are all the arms 27. In

Y the louvers are shown in closed position. VI-Iere the free or outeredge portion or A y 'margin of each arm 27 engages for its full lengththe attached or inner edge portion or margin of the arm 27 of the louvernext adjacent it (below it as disclosed in the drawing),

to effect a positive closing between all of the louvers. Specialprovision must be made to close the spaces of the ventilator betweenoutermost louvers and the frame members or plates 1() and 11,respectively. l Fig. 3 clearly discloses a manner in which these spacesare closed without the employment of fixed louvers. As there shown, thebody of the frame member or plate 10 includes a surface 44 extending thefull length of said member or plate 10, which is approximately parallelwith the flanges 16 and about in the plane of the arms 27 of the louverswhen closed, so that the full length of the attached or inner edgeportion or margin of the adjacent outermost arm 27 can be engaged bysaid surface 44 when the louvers are closed, in about the manner thatthe' inner edge portion or margin of each other louver is engaged by theouter edge portion of an adjacent louver. Similarly, the body of theframe member or plate 11- includes a surface 45 extending thelength ofAsaid member or lplate 11-, which is also approximately'parallel withthe flanges 16 and about in the plane of the arms 27 when closed, sothat the full length of the free or outer edge portion or marginy of the'adjacent outermost arm 27 can engage said surface 45 for its fulllength.

It should be remarked that'the end portion of the member or'plate 11adjacent the memberor plate13 is cutaway to clearthe'imanipulating lever(see F ig. 3), although the construction could be such thatsaid. member'or plate 11 and the manipulating lever 34 are Y' always spaced apart,as will be apparent.

In addition to providing the surfaces 44 and 45,. the members or plates10 and 11, respectively, should provide surfaces adapted to readilyreceive screws, or other attaching means whereby the'ventilator can beincor porated in a structure such as indicated at A in Fig. 2. -As moreclearly disclosed in Figs. 2, 3, 4 and 5,the surface4 44 of the plate 10merges in a surface 46 which is between the surface 44 and a flange 14,and the surface 45 of the plate 11 merges in'a surface 47 between thesurface 45 and a flange 15. These surfaces have holes to receive screwsB, or other attaching means, and are desirably obliquely disposed insuch manner as to render easy the insertionof the screws in the plates10 and 11 of the ventilator and in a structure such as represented at A.The remaining portions of the bodies of the members or plates 10'and11can be of any suitable structure, so long as there is not interferencebetween said 'bodies and thelouvers.

In assembling the louverswith the frame 12. I desirably'utilize rivets48 as .suggested in Fig. 6, to first secure the ears 24 to said member12. I may also utilize rivets to secure the ears 26 to the frame member13.

The ventilator as illustrated anddescribed Each louver with its Theoperating mechanism consists of'an operating bar and a manipulatinglever associated in novel and improved manner with a frame member andwith the operating bar. The elements going to make the ventilator arerelatively few and the positions of all of the elements are positivelyinsured, no liability whatsoever existing that any element can becomedislocated or impaired. Hence, the ventilator is durable, reliable andefficient for a long period of time.

To incorporate the ventilator in its position of use, all that isnecessary is to fit the frame. into an opening, the flanges of the framemembers or plates 12 and 13 ,serving the purpose of inclosing the endsof all of -the louvers, andthe surfaces 44' and 45 of the frame membersor plates 10 and 11, -respectively, interlapping withoutermost louverswhe'n in closed position to preserve the advantageous features of theventilator.

By reference to Figs. 2 and 3, it will be seen that I have soconstructed the vbody por-v tion of the frame member or plate 11 as toinsure that it will have no vhorizontal sur.

faces or cavities to serve as receptacles for dirt, dust, etc., and Ihave so arranged said -body portion that it can be readily dusted orcleaned. i

Frame members or plates constructed after rthe incorporation of thefinished ventilator in a structure, such as A, a simple task, mucheasier to accomplish than when all of the members or plates'of aventilator are like the 4plates 12, 13.

Having thus fully described the invention,

' what I claim as new and desire to secure-by yLetters Patent is L 1. Asan article of manufacture, a device comprising a rectangular frameconsisting of joined metallic channel pieces, opposite channel pieceshaving their marginal por.
